Build failure is spurious again, and unrelated to the changes. From the log it appears to maybe be hitting a 10 min timeout?
Indeed. @stefan_schmidt could you find a way to fix this? I.e. avoid marking those builds as failed if it's just a matter of timeout, or increase the timeout, or schedule the jobs so that the workload isn't insane, etc... I have no idea what could be done there with Jenkins but we get a lot of false alarms in the tickets here. As a consequence I just ignore Harbormaster :(
